Delta 3 Carene Molecule

Carene is a bicyclic monoterpene with a unique propanol ring;is has a sweet citrusy odor. Carene has been implicated in helping differentiate and stimulate calcium production in bone cells. The terpene is also effective as a toxin for mosquitos.

Bone growth:

Carene exposure was examined in the differentiation process of mouse osteoblastic MC3T3-E1 cells, which are involved in making bone structure. Carene was found to help stimulate differentiation of the cells. On differentiated cells, carene significantly promoted the induction of calcium, a key sign of bone mineralization.


Brazilian pepper oil, its main constituent being carene, was proven to be as an insecticide for S. Aegypti, yet safe for other aquatic organisms. The terpene was also shown to be a repellant as well in a separate study. The synergistic effect of coumarins, flavonoids and terpenes from the Lippia javanica extract had an additive effect on the repellency. One more study also inferred the toxicity of carene on two other human disease vector mosquitoes, Cx. quinquefasciatus and An. gambiae.
